FIELD OF THE INVENTION

The present disclosure relates to a display apparatus.

DISCUSSION OF THE RELATED ART

With the advancement of the information age, the demand for a displayapparatus for displaying an image has increased with various forms.Therefore, various types of display apparatuses such as a liquid crystaldisplay (LCD), a plasma display panel (PDP) and an electroluminescencedisplay (ELD) have been recently used. The electroluminescence displayapparatus may include a display apparatus such as an organic lightemitting display (OLED) and a quantum-dot light emitting display (QLED).

Among the display apparatuses, the electroluminescence display apparatusis a self-light emitting type, and has advantages in that a viewingangle and a contrast ratio are more excellent than those of the liquidcrystal display (LCD). Also, since the electroluminescence displayapparatus does not require a separate backlight, it is advantageous thatthe electroluminescence display apparatus is able to be thin andlightweight and has low power consumption. Furthermore, theelectroluminescence display apparatus has advantages in that it may bedriven at a low direct current voltage, has a fast response speed andespecially has a low manufacturing cost.

Meanwhile, in an electronic apparatus that includes anelectroluminescence display apparatus, the electroluminescent displayapparatus may include a display area provided with a pixel and a cameradisposed in an area overlapped with the display area. When the cameraoperates and then the pixel overlapped with the camera emits light, aproblem may occur in that photographing quality of the camera isdegraded by light emitted from the pixel. In the related art, in orderto solve the above problem, a method of increasing transmittance byomitting an anode electrode of a light emitting element in the areaoverlapped with the camera or omitting an entire pixel circuit of thearea overlapped with the camera has been used.

However, when the method is used, in the display area, the number ofpixels that emit light in the area overlapped with the camera is lessthan the number of pixels that emit light in the area that is notoverlapped with the camera, whereby a problem may occur in thatluminance of the display apparatus is reduced.

SUMMARY

The present disclosure has been made in view of the above problems andit is an object of the present disclosure to provide a display apparatusthat minimizes its luminance reduction while preventing photographingquality of a camera from being deteriorated.

In addition to the objects of the present disclosure as mentioned above,additional objects and features of the present disclosure will beclearly understood by those skilled in the art from the followingdescription of the present disclosure.

FIG. 3 is a circuit view illustrating a first display area DA1 of alight emitting display apparatus 100 according to one embodiment of FIG.2 .

The first display area DA1 may include a plurality of subpixels SPdisposed in the form of a matrix, and FIG. 3 illustrates first to fourthsubpixels SP1 to SP4 disposed in the form of a matrix. Each of the firstto fourth subpixels SP1 to SP4 may include a light emitting element LEDand a pixel circuit PC that independently drives the light emittingelement LED. The light emitting element LED may be an organic lightemitting diode, a quantum-dot light emitting diode, or an inorganiclight emitting diode, but is not limited thereto. Hereinafter, theorganic light emitting diode will be described by way of example.

Referring to FIG. 3 , the first subpixel SP1 may include the lightemitting element LED, and a first pixel circuit PC1 for driving thelight emitting element LED. The first pixel circuit PC1 may include adriving TFT DT, a compensation TFT T1, a switching TFT T2, an operationcontrol TFT T3, a light emission control TFT T4, an initialization TFTsT5 and T6, and a storage capacitor Cst.

The compensation TFT T1 may be turned on by a gate signal Gn suppliedthrough a gate line GLn to connect a gate electrode with a drainelectrode of the driving TFT DT, thereby connecting the driving TFT DTwith a diode structure.

The switching TFT T2 may be turned on by the gate signal Gn suppliedthrough the gate line GLn to supply a data signal Dm supplied through adata line DL to a source electrode of the driving TFT DT.

The operation control TFT T3 may be turned on by a light emissioncontrol signal EMn supplied through a light emission control line EL toconnect a second node N2, to which a first power voltage EVDD issupplied through a power line PL, with the source electrode of thedriving TFT DT.

The light emission control TFT T4 may be turned on by the light emissioncontrol signal EMn supplied through the emission control line EL toconnect the drain electrode of the driving TFT DT with an anodeelectrode of the light emitting element LED.

The first initialization TFT T5 may be turned on by a previous gatesignal Gn-1 supplied through a previous gate line GLn-1 to initialize afirst node N1 connected to the gate electrode of the driving TFT DT to afirst initialization voltage Vint1 supplied through a firstinitialization voltage line VL1.

The second initialization TFT T6 may initialize the anode electrode ofthe light emitting element LED to a second initialization voltage Vint2supplied through a second initialization voltage line VL2 in response tothe gate signal Gn supplied through the gate line GLn.

The storage capacitor Cst may charge a differential voltage between thedata signal Dm supplied to the first node N1 through the driving TFT DT,the compensation TFT T1 and the switching TFT T2 and the first powervoltage EVDD supplied to the second node N2 through the power line PLand supply the charged voltage to the driving TFT DT as a drivingvoltage.

The driving TFT DT may control a driving current flowing to the lightemitting diode LED in accordance with the driving voltage charged in thestorage capacitor Cst, thereby controlling light emitting intensity ofthe light emitting element LED in accordance with the driving current.

Therefore, the first subpixel SP1 may emit light by driving the lightemitting element through the first pixel circuit PC1.

Since each of the second to fourth subpixels SP2 to SP4 of the firstdisplay area DA1 includes a first pixel circuit PC1 configured to be thesame as the first subpixel SP1, its description will be omitted.Therefore, as the plurality of first pixel circuits PC1 drives the lightemitting element LED, the first display area DA1 may display an image.

FIG. 4 is a circuit view illustrating a second display area DA2 of alight emitting display apparatus 100 according to one embodiment of FIG.2 .

The second display area DA2 may include a plurality of subpixels SPdisposed in the form of a matrix, and FIG. 4 illustrates first to fourthsubpixels SP1 to SP4 disposed in the form of a matrix. At least one ofthe first to fourth subpixels SP1 to SP4 may include a light emittingelement LED and a pixel circuit PC that independently drives the lightemitting element LED. The light emitting diode LED may be an organiclight emitting diode, a quantum-dot light emitting diode, or aninorganic light emitting diode, but is not limited thereto. Hereinafter,the organic light emitting diode will be described by way of example.

Referring to FIG. 4 , the third subpixel SP3 includes a first pixelcircuit PC1, and the first, second and fourth subpixels SP1, SP2 and SP4may include a second pixel circuit PC2. In addition, although the thirdsubpixel SP3 includes a light emitting element LED, the first, secondand fourth subpixels SP1, SP2 and SP4 may not include a light emittingdiode LED. That is, the third subpixel SP3 may emit light, but thefirst, second and fourth subpixels SP1, SP2 and SP4 may not emit light.Therefore, the number of light emitting elements LED provided in theunit area of the second display area DA2 may be less than that providedin the unit area of the first display area DA1. Alternatively, in thefirst display area DA1 and the second display area DA2 with the samenumber of subpixels, the number of light emitting elements LED providedin the second display area DA2 may be less than that provided in thefirst display area DA1. Alternatively, the density of light emittingelements LED provided in the second display area DA2 may be smaller thanthat of light emitting elements LED provided in the first display areaDA1. At this time, the camera unit CM is disposed in an area overlappedwith the first, second and fourth subpixels SP1, SP2 and SP4 so thatdegradation of photographing quality of the camera due to light emittedfrom the subpixel may be minimized.

Since transistors constituting the first pixel circuit PC1 of the thirdsubpixel SP3 include the same configuration and features as those of thetransistors constituting the first pixel circuit PC1 described in FIG. 3, their description will be omitted.

The first subpixel SP1 may include a second pixel circuit PC2. Thesecond pixel circuit PC2 may include a driving TFT DT, a compensationTFT T1, an operation control TFT T3, a light emission control TFT T4,initialization TFTs T5 and T6, and a storage capacitor Cst. That is, thesecond pixel circuit PC2 may be a circuit in which the switching TFT T2is omitted from the first pixel circuit PC1. Therefore, since theswitching TFT T2 is not provided, the driving TFT DT may not be suppliedwith the data signal Dm.

Also, since transistors constituting the second pixel circuit PC2include the same configuration and features as those of thecorresponding transistors constituting the first pixel circuit PC1described in FIG. 3 , their description will be omitted.

Since the second and fourth subpixels SP2 and SP4 of the second displayarea DA2 include the second pixel circuit PC2 configured in the samemanner as the first subpixel SP1, a description thereof will be omitted.

In this case, the first to fourth subpixels SP1 to SP4 may beelectrically connected to one another. In detail, the first and secondpixel circuits PC1 and PC2 may have a third node N3 to which a drainelectrode of the operation control TFT T3 and the source electrode ofthe driving TFT DT are connected. The third nodes N3 respectivelyprovided in the first to fourth subpixels SP1 to SP4 may be electricallyconnected to one another. In this case, a current flowing to the thirdnode N3 provided in each of the first, second and fourth subpixels SP1,SP2 and SP4 may be supplied to the third node N3 of the third subpixelSP3. Therefore, the amount of the current supplied to the driving TFT DTof the third subpixel SP3 may be increased.

In addition, the first and second pixel circuits PC1 and PC2 may have afourth node N4 to which the light emission control TFT T4 and the secondinitialization TFT T6 are connected. The fourth nodes N4 respectivelyprovided in the first to fourth subpixels SP1 to SP4 may be electricallyconnected to one another. In this case, the current flowing to thefourth node N4 provided in the first, second and fourth subpixels SP1,SP2 and SP4 may be supplied to the fourth node N4 of the third subpixelSP3. Therefore, the amount of current supplied to the light emittingelement LED of the third subpixel SP3 may be increased.

Therefore, a circuit may be formed such that the current flowing to thefirst, second and fourth subpixels SP1, SP2 and SP4 flows to the thirdsubpixel SP3, whereby the current flowing to the third subpixel SP3 maybe increased. Therefore, luminance of the light emitting element LEDprovided in the second display area DA2 may be more improved than thelight emitting element LED provided in the first display area DA1.

In the present disclosure, as the light emitting element LED is notformed in some subpixels disposed in the second display area DA2,transmittance of the second display area DA2 may be improved. Also, thecurrent flowing to the light emitting element LED provided in the seconddisplay area DA2 may be increased more than the first display area DA1,whereby luminance of the light emitting element LED in the seconddisplay area DA2 may be improved. Therefore, overall luminancedegradation of the second display area DA2 may be reduced, wherebyluminance of the entire display area may be uniformly implemented.

In FIG. 4 , the third subpixel SP3 includes a light emitting element LEDand a first pixel circuit PC1, and the first, second and fourthsubpixels SP1, SP2 and SP4 include a second pixel circuit PC2, but thesesubpixels are not limited thereto. For example, at least one of thefirst to fourth subpixels SP1 to SP4 may include a light emittingelement LED and a first pixel circuit PC1, and the other subpixels mayinclude a second pixel circuit PC2.

FIG. 5 is a circuit view illustrating a second display area of a lightemitting display apparatus according to another embodiment of FIG. 2 .

Referring to FIG. 5 , the third subpixel SP3 includes a light emittingelement LED and a first pixel circuit PC1, and the first, second andfourth subpixels SP1, SP2 and SP4 may not include a light emittingelement LED and a pixel circuit PC. Since the first, second and fourthsubpixels SP1, SP2 and SP4 do not include a light emitting element LEDand a pixel circuit PC, transmittance of the second display area DA2disclosed in FIG. 5 may be further improved.

Since transistors constituting the first pixel circuit PC1 of the thirdsubpixel SP3 include the same configuration and features as those of thetransistors constituting the first pixel circuit PC1 described in FIG. 3, their description will be omitted.

In this case, an element structure of the driving TFT DT disposed in thefirst pixel circuit PC1 may be changed to increase a magnitude of acurrent flowing to the light emitting diode LED. For example, a width ofa channel area of the driving TFT DT disposed in the first pixel circuitPC1 may be increased. Therefore, the amount of current supplied to thedriving TFT DT disposed in the first pixel circuit PC1 may be increasedto increase the magnitude of the current supplied to the light emittingelement LED.

Alternatively, the data signal Dm supplied to the first pixel circuitPC1 may be adjusted to increase the magnitude of the current flowing tothe light emitting diode LED. For example, a supply algorithm of thedata signal Dm supplied to the data driver 30, the timing controller 40or the host processor 50 may be changed to adjust the data signal Dmsupplied to the data line DL. At this time, a magnitude of a voltage ofthe data signal Dm supplied to the driving TFT DT disposed in the firstpixel circuit PC1 provided in the second display area DA2 may beincreased. Therefore, the amount of current supplied to the driving TFTDT disposed in the first pixel circuit PC1 may be increased, whereby themagnitude of the current supplied to the light emitting element LED maybe increased.

In the present disclosure, as the light emitting element LED and thepixel circuit PC are not provided in some subpixels of the seconddisplay area DA2, transmittance of the second display area DA2 may beimproved further. Also, the current flowing to the light emittingelement LED provided in the second display area DA2 may be increasedmore than the first display area DA1, whereby luminance of the lightemitting element LED may be improved. Therefore, overall luminancedegradation of the second display area DA2 may be reduced, wherebyluminance of the entire display area may be uniformly implemented.

In FIG. 5 , the third subpixel SP3 includes a light emitting element LEDand a first pixel circuit PC1, and the first, second and fourthsubpixels SP1, SP2 and SP4 do not include a light emitting element LEDand a pixel circuit PC, but these subpixels are not limited thereto. Forexample, at least one of the first to fourth subpixels SP1 to SP4 mayinclude a light emitting element LED and a first pixel circuit PC1, andthe other subpixels may not include a light emitting element LED and apixel circuit PC.

According to the present disclosure, the following advantageous effectsmay be obtained.

According to the present disclosure, the current flowing to the pixel ofthe area overlapped with the camera may be increased to minimizeluminance reduction of the display apparatus.
